Video: Family finds pricey diamond

MURFREESBORO, Ark. — An Oklahoma state trooper making his first visit to Crater of Diamonds State Park on Sunday found a 4.21-carat crystal-shaped diamond, according to the Arkansas Parks and Tourism Department.

Martin Culver of Nowata, Okla., and his family decided on the spur of the moment to visit the park after watching a feature on the park Saturday on The History Channel, the agency said in a news release.

Culver said he would name the flawless, canary-yellow gem — the largest of 84 found in the park this year — the Okie Dokie Diamond, since no other diamond found in the park had been named for Oklahoma.

Crater of Diamonds State Park is the world's only diamond-producing site open to searching by the public.
